Need inspiration, restoration, or meditation? Synch up your brain waves with pulsing lights and sounds.


Relax and rejuvenate with the Brain Machine Kit  as your brain synchronizes to a wonderful meditative state.


Sound and Light Machines (SLM) essentially play a recording of brain waves into your brain by producing sound and light pulses at brain wave frequencies. With this kit, you build your own SLM and experience "hacking" your brain, taking it into deeper levels of consciousness by synchronizing it to light and sound programs associated with the meditation experience - or program it for sleep or deep thought.


Build your own machine to expand your brain's technical skills, then lean back and enjoy the light show. The brain machine is a hit at parties, enjoyed by those who enjoy meditating, and a favorite of those who just want to "trip out" on the wild colors and patterns produced by the subconscious.


Note: The picture featuring Mitch Altman, the co-designer, is of a previous version featured in MAKE magazine. The latest version does not include a serial port.


The current version of the Brain Machine does not follow the instructions of the previous version featured in MAKE Volume 10 or on the Brain Machine Page at (This kit is an update for an easier build.) The most up-to-date instructions for this kit are found under the How To tab. Basic soldering is required.


Safety note: The Brain Machine works with blinking lights. Be aware that blinking lights are not good for some people, especially those prone to seizures.

The Brain Machine Kit is an unassembled DIY kit - all the parts needed to make it are included: High quality Printed Circuit Board All electrical components, including pre-programmed microcontroller, wires, LEDs Over-ear headphones Dark-tinted safety glasses (fits children and adults) Color printed overlay for fashionability 2 x AAA batteries included - will last for hundreds of 'trips' The Kit does not include basic tools. You will need to provide the tools necessary for construction including a soldering iron, diagonal cutters, drill, hot glue (or other adhesive), scissors, etc. For the list of tools you'll need, please check the project prep page. The project is not very difficult and can be constructed in 2-3 hours at a leisurely pace by someone with no soldering experience. We have plenty of testing spots to help you along.
The brain produces varying proportions of brain wave types, depending on its current levels of relaxation, focus, and other mental states. Each type of wave has its own characteristic frequency range, which can be read by electroencephalography. Many people's brain waves will synchronize to lights and sounds pulsing at brain wave frequencies, and this makes the brain change its state -- a process called "entrainment." By playing sequences of pulses into your eyes and ears, you can program your brain to follow any brain wave experience you like.
